Characterizing the Nature of a Multi-Regional Trucking Network Using the Network Robustness Index: An Application to Ontario, Canada

Abstract Freight activity and economic productivity rely heavily on a robust road transportation network. Robustness refers to a network’s ability to withstand disruptions and is represented here by the change in network-wide travel time using the Network Robustness Index (NRI). Network disruptions can potentially severely degrade the network’s functionality and diminish regional trade. Such effects can be far-reaching into a transportation …
